This invention relates torazors. and it has particular reference tocertain new and .useful improvements in safety razors.

The principal object of the invention is to provide a safety razorhaving a head of triangular shape to accommodate a blade of analogousshape, provided with two sharpened cutting edges converging into a sharppoint, the purpose-of which is to enable one to reach and sever beard inotherwise inaccessible places such as in facial cavities adjacent thenostrils, in. wrinkles and other depressions in which beard :cannot beremoved by the conventional safety razor.

Another object of the inventionis to provide a razor which, by virtue ofthe triangular blade, will sever the beard by oblique engagementtherewith of the cutting edges of the blade "without likelihood ofcutting the skinQ In this manner, the beard is removed more effectivelyand without the attendant pull which results byymoving the conventionalrazor directly againstthe beard. i

Another object of the invention is to provide a head having a pivotedguard or shield conceal ing the blade and which is spring actuatedtoopen position when latching means are released by axial manipulationof aplunger contained in the handle of the razor.

Another object of the invention is toprovide a novel form of plungeractuated means for hold.

ing the pivoted guard or shield in closed and operative relation to thehead proper and which means consists of a spring bridge, the extremitiesof which are bent and formed into retainers for the pivoted guard but sodisposed and related to the plunger that depression thereof willdisplace the spring ends to release the guard to the influence of aseparate spring to snap the guard to open position. .1 1 With theforegoing objects as paramount, the invention has further reference tosalient features of accomplishment, to become apparent as the inventionproceeds, taken in connection with the accompanying drawingwherein:

Figure 1 is a perspective View of a safety razor constructed accordingto the present inventionl Figure 2 is a detail view in perspective ofthe head showing the guard in dottedlines. l it Figure 3 is a verticalsectional view of the hea theinner faceof the guard 23,when the guard ofthe handle next adjacent to the head, showing in detail, the guardlatching and releasing means. i

Continuing with a more detailed description of the drawing, the razor isprovided with ahol: low handle l0, preferably knurled, as shown, inwhich is axially mounted a plunger ll, one end of which extends slightlybeyond the end of the handle. Further reference to this plunger and-itspurpose willbe made presently. 1

Thehead of the razor is of triangular shape and consists of a;plate orportion 12, stationary with respect to the handle I0 and to which thehandle is rigidly attached. In Figures 3 andfi the form of securementbetween the handle and head is shown. The handle is bifurcated and thetwo legs l3 are aflixed to the plate [2 to de-. line a transverseopening edge of the head. 1

Extending through the opening [4 a mem to that of the spring member 15and. which notches receive the spring at points spaced from either endand the midsection thereof. The pur pose of these bridges is twofold,namely, to hold the spring against lateral displacement and to resistmovement of its ends towards the plate 12 when its midsection is sourged by pressure upon the end of the plunger I I. i

It is apparent that when the tip of the plunger II is urged inwardly,pressure of its end l9 upon the middle of spring I5 will warp the same,causing its ends IE to retract, by reasonof the bridges l8. An exampleof the displacementof the spring ends is shown'in Figure 5Yin dottedlines. The purpose of this operation will now be described...

' It will be observed that the ends I5 of 'the spring 15 which extendthrough the slots ll of the plate l2 are each provided with confrontingThese protuberances correspond to and are receivedin small depressionsll protuberances 20.

in projections -22 afiixedto and extending from is in closed position.It is through this medium that the guard is held in position until it isdesired to open the same to change blades.

l l parallel withthe top flange 24 along its top edge which overreachesthe top edge of the plate I2 and at either end of this flange, cars 25are provided and apertured to correspond with similar apertures in ears28 on the plate l2, A pin 21 extends across the plate I2 immediatelybelow its top edge and its ends are journaled in the apertures of theears 25 and 26, providing a hinge for the guard 23. A torsion spring 28is so arranged on the pin 21 as to swing the guard 23 to open position,a shown in dotted lines in Figure 2, when the latches are released inthe manner described, i. e., by pressing the plunger II.

The blade 29, shown in detail in Figure l is of triangular shape and hastwo cutting edges a, converging into a sharp point D. The object inproviding this point is to afford a means for shaving off beard growingin facial cavities and inaccessible places otherwise. The point isadequately shielded to protect the slain while shaving, yet withoutinterfering with its eifectiveness for the purpose intended. The bladeis further provided with an aperture 38, preferably triangular in shapeand located centrally thereof to receive a correspondingly shapedprotuberance 3| inthc center of the plate l2, (Figure 2). The blade isthus held against displacement in the head and its edges are kept inproper relationship with the serrated edges cof the guard 23.Furthermore, the blade 29 has slots 32 which, when the blade is mountedin the head, receive the ends I6 of the spring H) which extend throughthe slots H of the plate 12. The blade, by reason of the openings 33 ismade highly flexible so that its cutting edges will adjust themselvesclosely to the guard and plate I2.

In operation, the plunger ll whose inner end l9 enters an aperture inthe middle of spring IE to prevent longitudinal displacement,isdepressed which causes the spring to warp and its ends IE to retractpartially from slots of the plate 12. Not only are the ends it thusdisplaced, but they also move outwardly away from each other. While thismovement is but slight, it is sufficient to release the protuberances 20thereof from the depressions 2| of the projections 22 and-allow thetorsion spring 28 to swing the guard plate 23 away from the plate I2. Inthis manner, the head is opened to remove and replace the blade 29,after which the guard 23 is snapped shut, the spring l having in'th'emeantime resumed its original shape to return the endsl E to a positionto again operate to latch the guard plate to the plate [2.

Manifestly, the construction as shown and described is capable of somemodification and such modification as may be construed within the scopeand meaning of the appended claims is also considered to be within thespirit and intent of the invention.

What is claimed is:

l.
